However, the hacking group has warned people that it is not "affiliated" with Anonyupload and alleged that the site is a "scam".

Posting on the @YourAnonNews Twitter page, the group said: "FYI - We have NO affiliation with this site, and by the looks of it, this is a SCAM - anonyupload.com."

In a message on its website, Anonyupload insisted: "So, we will open Friday, because without money, we can't buy servers, bandwidth.

"Trust me, we are not trying to SCAM people. Thank you! We are setting up servers. Each user gets a FTPs access, which can be used to safely transfer files."

After the closure of Megaupload, various other sites have moved to shut down or limit their file-sharing functions to avoid the attention of US authorities.

Filesonic has disabled its sharing functions to only allow users to access their own files, while Uploaded.to has blocked US access to its site entirely. A message says "sorry about that".

The FileServe site has now done the same, posting the following message to users: "FileServe can only be used to download and retrieve files that you have uploaded personally. If this file belongs to you, please login to download it directly from your file manager."
